The SYSTEM-500 consists of Eurorack format modules that you can mix and match in any combination to create the ultimate Roland modular synthesizer. Each module is completely analog and has been designed for maximum compatibility with the world of contemporary synthesizer and effects modules. The SYSTEM-500 is a compact, powerful system that opens vast possibilities for sound design and musical exploration.

Channeling inspiration from the Roland SYSTEM-100m's 150 and 165 modules, the SYS-555 is a five-in-one powerhouse that brings core utility functions to your modular setup, but with some new and interesting twists. The SYS-555 contains both traditional and non-traditional modulation sources applicable to any imaginable configuration or setup. With ring modulation, versatile sample and hold with seven waveforms and internal LPF, pink and white noise modes, LFO with internal ENV and VCA, and two CV controlled portamento circuits, your tonal shaping and modulation options are near infinite.
